Abstract RU 2070230 C1

FIELD: methods for passivation of metal surfaces. SUBSTANCE: method for passivation of metal surfaces more precisely, the surfaces of stainless steel, titanium, etc, in the equipment used in chemical processes in which such elements and compounds are formed which possess corrosive properties, for instance, temperature and pressure exceeding that under environmental conditions. The method provides for combination of the main passivating agent - oxygen (air) with, at least, a second agent in form of ozone. EFFECT: higher efficiency. 11 cl
